Description
Technical field
The present invention relates to the renovation process of the hydrophobic layer of liquid discharge nozzle and liquid discharge nozzle.
Background technology
In the prior art, for example, in the situation of using the liquid quantitative discharger to distribute, by the nozzle coating liquid.Wherein, nozzle is made by non-corrosive metal such as stainless steels usually.Therefore, in the method that the nozzle outlet front end is detained, adopted the method that forms hydrophobic membrane at nozzle as the drop that suppresses to discharge from the nozzle of liquid discharging head.
But, directly use the hydrophobic membrane that forms on the nozzle that comprises the non-corrosive metal such as stainless steel or the nozzle to peel off, the easy attaching liq of nozzle outlet front end then, minute timing because the quantitative change of dripping at first is large, exists the amount of dripping and the bad problem of droplet profile.This phenomenon especially becomes problem to the LED encapsulation that contains fluorescent material with minute timings such as camara module relevant with contact area.
As the method for the delay liquid of removing such nozzle outlet front end, at the liquid quantitative discharger decompressor that is called the resorption bag is installed, adopt the method with the delay liquid resorption of spray nozzle front end.But, even after using the resorption bag, the drop that also spray nozzle front end can not be adhered to is removed fully.The result is, discharging continuously in the process of drop, As time goes on, even hydrophobic membrane is also adhered to dirt, particle in the liquid causes hydrophobic membrane physically to peel off, the outlet front end attaching liq of nozzle produces and is detained drop, is difficult to avoid occurring discharge rate and the inhomogenous situation of droplet profile.In addition, because the difference of the thickness of the degree of roughness on nozzle inside and outside wall surface and spray nozzle front end all can exert an influence to being detained drop.On the other hand, as the nozzle that machining accuracy is improved, the example of the nonmetallic materials such as the ruby outside the use metal or pottery is a lot, but the nozzle price becomes expensive, therefore, expects technology cheap and that can evenly be coated with.
Therefore, in order to address this problem, for example, patent documentation 1-3 discloses liquid discharging head, as shown in Figure 5, in order to reach the durability of hydrophobic membrane, nozzle 100 is disclosed, its following obtaining: on nozzle plate 101 surfaces basalis 102 is set, has formed plated film or the Organic hydrophobic membrane 103 of adding fluorine on its surface.In addition, as other technology, disclosing and having scribbled fluorine in nozzle plate surface is water-repelling agent or silicone-based water-repelling agent.

Summary of the invention
But, above-mentioned existing liquid discharge nozzle, discharging continuously in the process of drop, although hydrophobic membrane is difficult to adhere to dirt, but when using for a long time, As time goes on, dirt can occur adhere to, or the particle in the liquid causes hydrophobic membrane physically to peel off, and exists the front end of nozzle to be detained the problem of drop.In addition, drop is when hydrophobic membrane occur to be solidified or hydrophobic membrane when adhering to other attachments, and such attachment etc. also is not easy to remove.The result is to cause spray nozzle front end to be detained drop.
And then discharging liquid is not the such low viscous printing ink of ink-jet, but has than printing ink in the situation of more full-bodied resin, in the liquid discharge nozzle, when the wetted area of liquid is large, can not easily discharge, and exists the problem stopped up occurs easily.
The present invention is directed to above-mentioned existing problem, its objective is the renovation process that the hydrophobic layer that can guarantee to obtain long-life liquid discharge nozzle and liquid discharge nozzle is provided, the result can prevent from stopping up, even attachment is peeled off or be attached with to hydrophobic layer simultaneously, hydrophobic layer also can easily be regenerated.
In order to address the above problem, liquid discharge nozzle of the present invention is characterised in that, possess and hold the liquid storage container of discharging liquid and the discharge portion that is communicated with this liquid storage container downside, the outlet front end of above-mentioned discharge portion, the inner wall surface of discharge portion and the inner wall surface of liquid storage container arrange hydrophobic layer, it is hydrophobic layer that above-mentioned hydrophobic layer of while comprises fluorine, be the basalis of hydrophobic layer as above-mentioned fluorine, use the stack membrane of alumina layer and silicon oxide layer, the above-mentioned alumina layer of lamination, silicon oxide layer and fluorine are that the film gross thickness of hydrophobic layer is below 25 nanometers, and above-mentioned fluorine is that the film thickness of hydrophobic layer is the 1-4 nanometer.
According to foregoing invention, possess and hold the liquid storage container of discharging liquid and the discharge portion that is communicated with this liquid storage container downside, the outlet front end of discharge portion, the inner wall surface of discharge portion and the inner wall surface of liquid storage container arrange hydrophobic layer.And it is hydrophobic layer that hydrophobic layer comprises fluorine, is the basalis of hydrophobic layer as fluorine, uses the stack membrane of alumina layer and silicon oxide layer.
That is, generally speaking, in the liquid discharge nozzle, the outlet front end of discharge portion arranges hydrophobic layer, and the inner wall surface of discharge portion does not arrange hydrophobic layer.Its reason is, originally think problem that nozzle is detained drop be owing to outlet outlet, be that the outlet front end delay drop occurs causes.In addition, the inner wall surface of discharge portion generally speaking, the flow velocity of liquid is fast, and hydrophobic layer is peeled off easily.
For this problem, among the present invention, the inner wall surface of discharge portion and the inner wall surface of liquid storage container all arrange hydrophobic layer.Like this because discharge liquid for example is not the such low viscous printing ink of ink-jet, but have than printing ink in the situation of more full-bodied resin, it is large that the interfacial tension of the inner wall surface of discharge portion etc. becomes, the wetted area of resin is diminished, the inner wall surface of discharge portion etc. and the surface adhesion force between the resin and less traction, the flowability of resin improves.
Therefore, among the present invention, the inner wall surface of discharge portion and the inner wall surface of liquid storage container all arrange hydrophobic layer, therefore in the inside of liquid discharge nozzle, even the high discharge liquid of viscosity also has the advantage that flowability improves.
But, in the inner wall surface of discharge portion, having when flow rate of liquid is fast or in the liquid in the situation of particle, the problem that physical property peels off occurs and still exists in hydrophobic layer easily.
Therefore, among the present invention, comprise the basalis of the stack membrane of alumina layer and silicon oxide layer hydrophobic layer setting.Consequently, the adhesive strength of hydrophobic layer increases, and hydrophobic layer is not easy to peel off, so durability is high.
In addition, among the present invention, above-mentioned alumina layer, silicon oxide layer and the fluorine of lamination is that the film gross thickness of hydrophobic layer is below 25 nanometers, and fluorine is that the film thickness of hydrophobic layer is the 1-4 nanometer.
And, good in order to obtain durability, the film thickness of the hydrophobic layer of existing liquid discharge nozzle, when for example processing coating Teflon (テ Off ロ Application) (registration mark) by dip-coating (dipping), its film thickness is about 100 microns.But for example, when the film gross thickness is set was hydrophobic layer about 100 microns, the internal diameter of discharge portion had large variation in the inner wall surface of discharge portion, and the deviation of film thickness increases the shape that also can affect nozzle inside diameter.The result also causes the variation of discharge rate.
Therefore, among the present invention, above-mentioned alumina layer, silicon oxide layer and the fluorine of lamination is that the film gross thickness of hydrophobic layer is below 25 nanometers.
Consequently, by long-time use, even As time goes on hydrophobic layer adheres to dirt, or because the particle in the liquid, when hydrophobic layer generation physical property was peeled off, the diameter of discharge portion can not change a lot yet.
And among the present invention, fluorine is that the film thickness of hydrophobic layer is the 1-4 nanometer.That is, like this with the film thickness attenuation, even when the part of hydrophobic layer is peeled off, perhaps droplet solidification when perhaps other attachments are attached to hydrophobic layer, for example passes through Cement Composite Treated by Plasma when hydrophobic layer, easily the attachment of hydrophobic layer and hydrophobic layer is peeled off, hydrophobic layer can be set again.
Consequently, the hydrophobic layer processing of regenerating easily can prolong life-span of liquid discharge nozzle thus.
Therefore, even can provide viscosity high discharge liquid, also have good fluidity, prevent from stopping up, even attachment is peeled off or be attached with to hydrophobic layer simultaneously, hydrophobic layer also can easily be regenerated, thus the liquid discharge nozzle of life-saving.
In order to address the above problem, the renovation process of the hydrophobic layer of liquid discharge nozzle among the present invention, it is the renovation process of the hydrophobic layer of above-mentioned liquid discharge nozzle, it is characterized in that, remove attachment and this hydrophobic layer that is attached to above-mentioned hydrophobic layer by at least a above method in plasma, ultraviolet ray irradiation or the neutralizing treatment, again form hydrophobic layer.
Namely, when the part of hydrophobic layer is peeled off, perhaps droplet solidification is when hydrophobic layer, when perhaps other attachments are attached to hydrophobic layer, by at least a above method in plasma, ultraviolet ray irradiation or the neutralizing treatment, cut off the combination of chemistry, hydrophobic layer is easily separated with the hydrophobic layer attachment, thereby be removed.And hydrophobic layer is that film thickness also is the such thin layer of 1-4 nanometer, therefore can easily be coated with hydrophobic layer again.
Therefore, can provide the hydrophobic layer that can guarantee long-life liquid discharge nozzle renovation process, the result can prevent from stopping up, even attachment is peeled off or be attached with to hydrophobic layer simultaneously, hydrophobic layer can both easily be regenerated.
Liquid discharge nozzle of the present invention, as mentioned above, possess and hold the liquid storage container of discharging liquid and the discharge portion that is communicated with this liquid storage container downside, the outlet front end of above-mentioned discharge portion, the inner wall surface of discharge portion and the inner wall surface of liquid storage container arrange hydrophobic layer, it is hydrophobic layer that above-mentioned hydrophobic layer of while comprises fluorine, be the basalis of hydrophobic layer as above-mentioned fluorine, use the stack membrane of alumina layer and silicon oxide layer, the above-mentioned alumina layer of lamination, silicon oxide layer and fluorine are that the film gross thickness of hydrophobic layer is below 25 nanometers, and above-mentioned fluorine is that the film thickness of hydrophobic layer is the 1-4 nanometer.
And, the renovation process of the hydrophobic layer of liquid discharge nozzle of the present invention, as mentioned above, it is the renovation process of hydrophobic layer of the liquid discharge nozzle of above-mentioned record, the method forms hydrophobic layer again by after at least a above method is removed the attachment and this hydrophobic layer that is attached to above-mentioned hydrophobic layer in plasma, ultraviolet ray irradiation or the neutralizing treatment.
Therefore, can provide the hydrophobic layer renovation process that can guarantee long-life liquid discharge nozzle and liquid discharge nozzle, the result has to prevent from stopping up, even attachment is peeled off or be attached with to hydrophobic layer, the effect that hydrophobic layer can both easily be regenerated simultaneously.

The specific embodiment
Based on Fig. 1 (a)-Fig. 4 one embodiment of the invention are described.
(structure of liquid discharge nozzle)
The structure of the liquid discharge nozzle of the present embodiment is described based on Fig. 1 (a), Fig. 1 (b), Fig. 2 (a) and Fig. 2 (b).Fig. 1 (a) shows the sectional view that has the aforesaid liquid discharge nozzle structure of conical liquid storage container and discharge pipe in the aforesaid liquid discharge nozzle, and Fig. 1 (b) is the sectional view of the hydrophobic layer that forms of the inner wall surface of the inner wall surface of the outlet front end that shows discharge pipe, discharge pipe and liquid storage container.In addition, Fig. 2 (a) is the front view that shows aforesaid liquid discharge nozzle structure, and Fig. 2 (b) is the bottom view that shows aforesaid liquid discharge nozzle structure.
The liquid discharge nozzle 1 of the present embodiment, for example, it is used for coating LED(Light Emitting Diode: the resin of fluorescent material light emitting diode), shown in Fig. 2 (a) and Fig. 2 (b), possess and hold the liquid storage container 10 of discharging liquid and the discharge pipe 20 that is communicated with these liquid storage container 10 downsides.
Above-mentioned liquid storage container 10 comprises the cylindricality liquid storage container 11 of upside formation and the conical liquid storage container 12 that downside forms.
Above-mentioned cylindricality liquid storage container 11 is combined to form cylinder with the conical liquid storage container 12 of downside, also is combined to form cylinder with conical liquid storage container 12 as the discharge pipe 20 of discharge portion.But, not one to be decided to be cylinder, integral body is that square tube also can.
The height H 1 of aforesaid liquid discharge nozzle 1 for example is 18 millimeters, and the height H 2 of conical liquid storage container 12 and discharge pipe 20 combinations for example is 6.5 millimeters.In addition, the outer diameter D of cylindricality liquid storage container 11 for example is 6 millimeters, and the front and back of the cylindricality liquid storage container 11 of liquid discharge nozzle 1 forms tabular surface, for example puts down in writing the drop discharge rate on this tabular surface.
Shown in Fig. 1 (a), the conical liquid storage container 12 of above-mentioned liquid storage container 10 is communicated with the discharge pipe 20 that the downside of this taper shape liquid storage container 12 arranges, and discharge pipe 20 has the internal diameter thinner than the internal diameter of conical liquid storage container 12 simultaneously.
In the liquid discharge nozzle 1 of the present embodiment, shown in Fig. 1 (b), the inside and outside wall surface 2 of conical liquid storage container 12 and discharge pipe 20 arranges hydrophobic layer 5.In addition, among the present invention, it is just enough at the inner wall surface 10a of the inner wall surface 20b of the outlet front end 20a of discharge pipe 20, discharge pipe and liquid storage container 10 hydrophobic layer 5 to be set at least.
Specifically, at the hydrophobic layer 5 that the inside and outside wall surface 2 of conical liquid storage container 12 and outlet 20 forms, comprising fluorine is hydrophobic layer, is provided as simultaneously to comprise the aluminium oxide (Al of basalis that fluorine is the hydrophobic layer 5 of hydrophobic layer
2O
3) layer 3 and at this aluminium oxide (Al
2O
3) layer 3 superimposed layer the silica (SiO as basalis
2) layer 4.
In addition, in the liquid discharge nozzle 1 of the present embodiment, on the inside and outside wall surface 2 of conical liquid storage container 12 and discharge pipe 20 hydrophobic layer 5 is set.But, be not limited thereto in the present invention, can be at least form hydrophobic layer 5 in the inner wall surface of conical liquid storage container 12 and discharge pipe 20.
In the present embodiment, the thickness of above-mentioned hydrophobic layer 5 is the 1-4 nanometer, hydrophobic layer 5 and as the aluminium oxide (Al of basalis
2O
3) layer 3 and silica (SiO
2) layer three layers of summation of 4 for example are below 25 nanometers.Be preferably below 20 nanometers.Reason is, hydrophobic layer 5 and as the aluminium oxide (Al of basalis
2O
3) layer 3 and silica (SiO
2) layer 4 three layers thickness surpasses 25 nanometers, after long-time the use, because the internal diameter of discharge pipe 20 changes, can cause the variation of the shape of discharge pipe 20.Specifically, the thickness of each layer in the liquid discharge nozzle 1 of preproduction for example: aluminium oxide (Al for example
2O
3) layer 3 is 10.5 nanometers, silica (SiO
2) layer 4 is 6.5 nanometers, the hydrophobic layer 5 that comprises fluorine and be hydrophobic layer is 1.2 nanometers.
(the formation method of the hydrophobic layer of liquid discharge nozzle)
The following formation method of hydrophobic layer 5 of the liquid discharge nozzle 1 of explanation said structure.
That is, in the present embodiment, at the aluminium oxide (Al of inside and outside wall surface 2 superimposed layers formation as basalis
2O
3) layer 3 and silica (SiO
2) layer 4, forming fluorine on it is hydrophobic layer (self-composed monomolecular).Like this, 3 layers film gross thickness is about 20 nanometers, does not affect the internal diameter shape of discharge pipe 20.
At first, use the method for vapor-phase growing of organic molecule, liquid discharge nozzle 1 is set in chamber, use the inside and outside wall surface 2 of oxygen plasma cleaning liquid discharge nozzle 1, make its activation.Then, heating reacting gas to 100 ℃ makes its gasification, imports in the chamber that is heated in advance 55 ℃, forms aluminium oxide (Al in this chamber
2O
3) layer 3.Subsequently, will be vented to 3-8Pa in this chamber, repetitive cycling forms the aluminium oxide (Al about 10 nanometers thus
2O
3) layer 3.
Then, in same chamber, use oxygen plasma to clean aluminium oxide (Al
2O
3) layer 3 above, make its activation.Then, heating reacting gas to 100 ℃ makes its gasification, imports and forms silica (SiO in the chamber that is heated in advance 55 ℃
2) layer 4.Subsequently, will be vented to 3-8Pa in this chamber, repetitive cycling forms the silica (SiO about 10 nanometers thus
2) layer 4.
Then, at silica (SiO
2) above layer 4 whole, forming fluorine is hydrophobic membrane.Like this, just formed film thickness and be the monomolecular film about the 1-4 nanometer.
(renovation process of the hydrophobic layer of liquid discharge nozzle)
Generally speaking, the hydrophobicity of the hydrophobic layer 5 of liquid discharge nozzle 1 is high, but oleophobic property is not safe against all possibilities, in the process that liquid is discharged repeatedly, can produce residue, causes hydrophobic performance to worsen.These such as the organic reagent washing of using acetone etc. to carry out, use ultrasonic washing that isopropyl alcohol (IPA) etc. carries out etc. to remove fully.Therefore, only removing the fluorine that the top layer on residue and inside and outside wall surface 2 forms by oxygen plasma is hydrophobic layer, and making becomes the silica of basalis (SiO
2) layer 4 exposes, under the state after the cleaning, again forming fluorine is hydrophobic layer.
Like this, the liquid discharge nozzle 1 of the present embodiment possesses and holds the liquid storage container 10 of discharging liquid and the discharge pipe 20 that is communicated with these liquid storage container 10 downsides, and the outlet front end 20a of discharge pipe 20, the inner wall surface 20b of discharge pipe 20 and the inner wall surface 10a of liquid storage container 10 arrange hydrophobic layer 5.And it is hydrophobic layer that hydrophobic layer 5 comprises fluorine, is the basalis of hydrophobic layer as fluorine, uses aluminium oxide (Al
2O
3) layer 3 and silica (SiO
2) layer 4 stack membrane.
That is, generally speaking, in the liquid discharge nozzle, the outlet front end of discharge pipe arranges hydrophobic layer, and the inner wall surface of discharge pipe does not arrange hydrophobic layer.Its reason is, thinks that problem that nozzle is detained drop is owing to the outlet of outlet, be that the outlet front end drop occurs to be detained causes originally.In addition, generally speaking, the flow velocity of the inner wall surface liquid of discharge pipe is fast, and hydrophobic layer is peeled off easily.
For this problem, in the present embodiment, the inner wall surface 10a of the inner wall surface 20b of discharge pipe 20 and liquid storage container 10 arranges hydrophobic layer 5.Like this because discharge liquid for example is not the such low viscous printing ink of ink-jet, but have than printing ink in the situation of more full-bodied resin, it is large that the interfacial tension of the inner wall surface 20b of discharge pipe 20 grades becomes, the wetted area of resin is diminished, inner wall surface 20b and the surface adhesion force between the resin and the less traction of discharge pipe 20 grades, the flowability of resin improves.
Like this, in the present embodiment, the inner wall surface 10a of the inner wall surface 20b of discharge pipe 20 and liquid storage container 10 arranges hydrophobic layer 5, therefore in the inside of liquid discharge nozzle 1, even the high discharge liquid of viscosity also has the advantage that flowability improves.
But at the inner wall surface 20b of discharge pipe 20, when flow rate of liquid is fast or owing to the particle in the liquid, the problem that hydrophobic layer 5 easy generation physical properties are peeled off still exists.
Therefore, in the present embodiment, setting comprises aluminium oxide (Al on the hydrophobic layer 5
2O
3) layer 3 and silica (SiO
2) basalis of layer 4 stack membrane.Therefore, the adhesive strength of hydrophobic layer 5 increases, and hydrophobic layer 5 is not easy to peel off, so durability is high.
In addition, in the present embodiment, the aluminium oxide (Al of lamination
2O
3) layer 3, silica (SiO
2) layer 4 and fluorine be that the film gross thickness of hydrophobic layer is below 25 nanometers, fluorine is that the film thickness of hydrophobic layer is the 1-4 nanometer.But forming film thickness is that the monomolecular film of hydrophobic layer is difficult less than the fluorine of 1 nanometer.On the other hand, fluorine is hydrophobic layer film thickness when surpassing 4 nanometer, and such as patent documentation 3 records like that, strand twines and the layer meeting thickening that obtains.But like this, causing fluorine is that hydrophobic layer is peeled off easily, is not preferred.
And good for durability, the film thickness of the hydrophobic layer of existing liquid discharge nozzle when for example processing coating Teflon (registration mark) by dip-coating (dipping), is about 100 microns.But for example, when the film gross thickness is set was hydrophobic layer about 100 microns, the internal diameter of discharge pipe had large variation in the inner wall surface of discharge pipe, and the deviation of film thickness increases, and can affect the shape of nozzle inside diameter.The result causes the variation of discharge rate.
Therefore, in the present embodiment, the aluminium oxide (Al of lamination
2O
3) layer 3, silica (SiO
2) layer 4 and fluorine be that the film gross thickness of hydrophobic layer is below 25 nanometers.
Consequently, by long-time use, even As time goes on hydrophobic layer 5 adheres to dirt, or because the particle in the liquid, when hydrophobic layer 5 generation physical properties were peeled off, large variation can not occur in the caliber of discharge pipe 20 yet.
And in the present embodiment, fluorine is that the film thickness of hydrophobic layer is the 1-4 nanometer.That is, like this with the film thickness attenuation, even when the part of hydrophobic layer 5 is peeled off, perhaps droplet solidification when perhaps other attachments are attached to hydrophobic layer 5, for example passes through Cement Composite Treated by Plasma when hydrophobic layer 5, easily the attachment of hydrophobic layer 5 and hydrophobic layer 5 is peeled off, hydrophobic layer 5 can be set again.
Consequently, hydrophobic layer 5 easily regeneration is processed, and can prolong thus the life-span of liquid discharge nozzle 1.
Therefore, even can provide viscosity high discharge liquid, also have good fluidity, prevent from stopping up, even attachment is peeled off or be attached with to hydrophobic layer 5 simultaneously, hydrophobic layer 5 also can easily be regenerated, thereby can guarantee long-life liquid discharge nozzle 1.
And in the liquid discharge nozzle 1 of the present embodiment, discharge liquid is resin material.Thus, because resin material has higher viscosity than printing ink, by with its discharge medium as the liquid discharge nozzle 1 of the present embodiment, can obtain the effect of the present embodiment largelyr.
In addition, the renovation process of the hydrophobic layer 5 of liquid discharge nozzle 1 in the present embodiment, after at least a above method is removed the attachment and this hydrophobic layer 5 that is attached to this hydrophobic layer 5 in plasma, ultraviolet ray irradiation or the neutralizing treatment, again form hydrophobic layer 5.
Namely, when repeatedly discharging liquid, when the part of hydrophobic layer 5 is peeled off, perhaps droplet solidification is when hydrophobic layer 5, when perhaps other attachments are attached to hydrophobic layer 5, by at least a above method in physical property machining, plasma, ultraviolet ray irradiation or the neutralizing treatment, cut off the combination of chemistry, the attachment of hydrophobic layer 5 and hydrophobic layer 5 is easily peeled off, thereby be removed.And hydrophobic layer 5 is that film thickness also is the such film of 1-4 nanometer, therefore can easily be coated with hydrophobic layer 5 again.
And, the removing in the method for above-mentioned various hydrophobic layer 5 grades, Cement Composite Treated by Plasma has oxygen plasma treatment or argon plasma to process.And the ultraviolet ray irradiation comprises ozone treatment.Like this, when removing hydrophobic layer 5 grade, can the Applied Physics machining process, chemistry removes method.
And, the removing in the method for above-mentioned various hydrophobic layer 5 grades, preferred argon plasma and oxygen plasma, most preferably oxygen plasma.Reason is: when forming hydrophobic layer 5 grade, form film in vacuum chamber.Therefore, argon plasma and oxygen plasma treatment also can be carried out in same vacuum chamber, and therefore, the liquid discharge nozzle 1 that tunicle forms object does not need to be exposed to atmosphere halfway.Like this, can not adhere to the suspension in the atmosphere, therefore can under the state of cleaning, form film.In addition, compare with argon plasma, oxygen plasma is more conventional, and is with low cost.
Like this, repeatedly discharge the deteriorated regeneration of following film of the film that causes at liquid, by processing such as oxygen plasmas, the fluorine of only removing the surface is hydrophobic layer, exposes the silica (SiO of basalis
2) layer 4, under the state after the cleaningization, can again form fluorine is hydrophobic layer.
Therefore, can provide the renovation process of the hydrophobic layer 5 that can guarantee long-life liquid discharge nozzle 1, the result can prevent from stopping up, even attachment is peeled off or be attached with to hydrophobic layer 5 simultaneously, hydrophobic layer 5 also can easily be regenerated.
In addition, the invention is not restricted to above-mentioned embodiment, within the scope of the present invention various variations can be arranged.For example, in the above-mentioned embodiment, the downside discharge pipe 20 of liquid discharge nozzle 1 is tubular, but is not limited thereto.That is, but liquid discharge nozzle of the present invention 1 application drawing 3(a), all types of liquid discharge nozzle shown in Fig. 3 (b) and Fig. 3 (c).
That is, the liquid discharge nozzle shown in Fig. 3 (a) 1 is the taper mode.The discharge portion of such liquid discharge nozzle 1 is taper, and in this discharge portion, flow velocity increases, and is not subjected to the impact of internal direct pipe arrangement resistance, keeps flow velocity.The resistance of this type liquid discharge nozzle 1 is little, and it is unstable and flow velocity is had harmful effect, quantitative easy variation to discharge liquid itself.
Secondly, the liquid discharge nozzle shown in Fig. 3 (b) 1 is taper+straight shape mode.The discharge portion of such liquid discharge nozzle 1 is straight shape, and flow velocity increases owing to the taper of upside, and internal diameter makes flow speed stability because the pipe arrangement resistance of the discharge portion of straight shape makes Speed Reduction with certain constant speed.The resistance of this type liquid discharge nozzle 1 is large, but quantitative height.
